Understanding the UV Index is crucial for residents of Hechun, China, where sunny days are frequent and UV exposure can vary significantly throughout the day. By being aware of UV levels, you can take proactive measures to prevent sunburn and promote long-term skin health. With a Cwa climate that often brings high levels of sun exposure, particularly from 10 AM to 2 PM when the UV Index peaks at 13, it's essential for individuals to stay informed and protect their skin. Embrace the sun while prioritizing your health!
As the day unfolds, the UV Index reveals a dynamic pattern of sun exposure that peaks during midday. Starting at a gentle 1 at 07:00, the index gradually climbs, reaching a moderate 5 by 09:00.

By late afternoon, the UV levels decrease to 5 by 16:00, and finally sink back to 1 by 18:00 and 19:00. It's a reminder of the sun's powerful rays—plan your outdoor activities accordingly!
